PEOCESS OF PRODUCING DYED FABRICS.

N'o Drawing.

To all whom it may concern:

Be it known that I, ELIAS Krnsorrnn- BAUM, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Processes of Producing Dyed Fabrics, of which the following is a specification.

This invention. relates to a process of producing dyed fabrics and is intended to be applicable to all manners of fabrics including woven, knitted, and braided textiles, and any form of fabric in which a process of the nature could be utilized.

The object of the invention is to produce fabrics of one or more colors by impregnating certain of the threads, yarns or other portions of the fabric prior to the time of weaving, knitting or braiding, with a superabundance of dye material which material is afterwards released so as to dye the adjacent threads, yarns, or other portions of the fabric when completed so as to form all manner of designs and mottled effects.

Another object is to produce dyed goods in a manner avoiding the present costly methods of effecting these results.

With these and other objects in view the process consists in certain operations, the nature and sequence of which will be hereinafter fully explained and will be particularly pointed out in the claims hereunto annexed.

In carrying out the present process, I have had in mind particularly, the making and dyeing of artificial silken tape and braid wherein it is very difiicult to pre-dye certain of the materials which are interwoven. In carrying out the process, certain of the threads which are of such nature as to readily adapt themselves to dyeing prior to being worked up into the fabric, are filled with a considerable quantity of dyestuff, the quantity being filled according to the shade and effect desired. I then work up this dyed material together with the other material which is light colored, white or in its natural color, and I then subject the entire fabric to a moistening treatment, either by placing it in a bath or by subject ing it to jets of steam or to other moistening agencies. If it is then desired that the color should be fixed, the goods may be treated with a mordant.

Serial No. 667,413.

It is to be remembered that in certain sorts of fabrics, ribbons, braids, gimp threads and l: threads are oftentimes woven into the fabric so as to form welts and other peculiarities in th fabric. If these various portions of the fabric have been pie-dyed according to the above mentioned process, the resulting fabric after wetting will have a very peculiar and ornamental eifcct which is also contemplated by the present invention.

It is also desired to point out that by excess dyeing of either part of the warp or part of the woof threads or part of both, and thereafter effecting the making up of the material and the moistening of the same, striped and checkered patterns may be obtained. It is also obvious that a number of different colors can be used in this way and can be run into each other in which case they would blend and harmonize with remarkable smoothness. Under these circumstances, it is contemplated that a number of varying forms of designs and fabrics can be produced. by utilizing the dyeing threads either for the entire warp, the entire filling or weft, for sections of either, for sections of both, for sections of the warp in knitted fabrics, and for sections of round or horizontally knitted fabrics. Like-- wise, for sections of braid without warp, for sections of the warp, or entire warp of the blaids, and for sections of various colors in any form of fabric.

As to the wetting operation, this may be as above stated, either with plain water or with steam or if found more effective on the dyes, then any form of suitable mechanical agent may be utilized for this purpose. According to the amount of dye which is placed in the fabric and according to the action which is permitted at the time of wetting, the fabrics may be turned out either in pattern, in mottled effects, or in plain solid colors.

It is also contemplated that the dye may be printed on the threads prior to the making up of the fabric, and then after the fabric is woven or otherwise made up, the wetting process will bring out the variously located color or colors so as to produce a mottled effect.

What I claim is 1. The herein described process of producing dyed fabrics which consists in manuiect ring fabric partly from undyed inaei'iai end pert-1y from material carrying an excess of dye and of then subjecting the entire fabric to a Wetting agent.

2. lhe herein described process of producing dyed fabrics which consists in dyecertein threads with an excess of dye material, then Weaving or otherwise uniting said threads with other undyed threads to form a fabric, and then. subjecting said fabric to it meistening agent.

3 The herein descrihet't process of producing dyed fabrics which consists in dyece'rtziiii threads with an excess of dye ducing dyed fabrics which consists in inanu- :tecturing 2t fabric partly from material carrying an excess oi? dye and partly from me- 1 net carrying an excess of dye, and of then siiiiijecting the entire fabric to a wetagent.

In testiineny whereof I efiix n y signature.
